7. The circuit as in diagram 4 is made up of eleven identical 1 ohm resistors connected to an 15v power supply.
Determine:
a)total resistance of the entire circuit
b) current from the power supply
c) current through resistor R1
d)current through resistor R2
e)current through resistor R3

An external consultant recommends that a plant installs a bank of capacitors for power factor correction. this will reduce the peak electrical demand charges by an average of 93 kw every month. the plant current pays $13 per kw in peak demand charges. the capacitor bank will include 223 kw of fixed capacitors, and 183 of variable capacitors. the fixed capacitors cost $59 per kw, and the variable capacitors will cost $65 per kw. the consultant charges 21% of the equipment costs to install the capacitors. because this project will reduce the demand for the electric utility, they are prepared to provide a one-time rebate of $42 per kw of reduced demand. what is the simple payback period for this project (in years)?
